The Lagotto Romagnolo was originally used as a water dog and is from the northeastern area of Italy known as Romagna. As the waterfowl disappeared in their area, they began to be used to find truffles. Truffles, being the most expensive food per ounce in the world, are more valuable than gold. The Lagotto Romagnolo is possibly the only breed with this kind of talent for finding truffles. They also make excellent companion dogs.
